Phenobarbital
for head tremoring in Bulldog
Question: Dr. Mike--
I'm sorry I keep bugging you but I want to give you as much info as
possible. Tubby had another seizure about an hour ago. It again lasted
about 8-10 min. and was the same kind as before. An intermintant shaking
of the head in an up and down motion. He is totally alert while he
is
doing it and will act as if nothing's wrong--chasing balls, getting
a
drink, etc...I called my vet and he decided to put him on a
phenobarbituate of 90 mg. daily. For the record, Tubby is an English
Bulldog. He is 16 months old and weighs about 62 lbs.
Any input would help.
thank you. Sergio
Answer: Sergio-
Phenobarbital has enough potential to cause serious side effects that
I
would hesitate to use it without getting an opinion from a veterinary
neurologist (if that is possible in your area) about the possible causes
of
the head tremoring, especially since this is a well recognized problem
in
bulldogs. I know that you are concerned but taking the time to get
a second
opinion from a specialist could be very beneficial. If there is not
a
neurologist in your area, there is probably an internal medicine specialist
who does some neurology work. Your vet should be able to refer you
to an
appropriate specialist.
The other side of this is that some vets really believe this is a seizure
disorder and there are some reports of phenobarbital helping with the
problem, even though there are a number of reports of it not helping,
as
well. So your vet is probably just following the advice of the experts
he
or she believes to be correct in this situation. Disagreements over
the
best approach to problems like this occur and sometimes you have to
be the
person responsible for deciding which ones to believe -- and you should
always give heavier weight to the opinion of someone who has actually
seen
your dog. But my advice would still be to try to get an appointment
with a
veterinary neurologist or internal medicine specialist before staying
on
phenobarbital long term.

Head tremors
in English Bulldog
Question: Dr. Mike--
Earlier this evening I noticed what my vet thinks may have been a
seizure in my Bulldog.
Tubby is about 15 months old and I have never seen anything like this
before. He was resting for about a half hour and then all of a sudden
woke up and started shaking his head violently up and down. The rest
of
his body was normal. I was so concerned that I jumped up and immeditely
took him to the ER. Even in the car, Tubby wanted to put his head out
the window. All along, still shaking his head violently. It all lasted
about 5-10 min. He seems to be fine now but I am very concerened. Is
there anything I should look for? Could this be caused by over
excitement? Yesterday I took him to a dog park and he ran around for
a
good 45 min to an hour. I'm telling you this because when he is so
energetic, it looks as if he is really exhausted but he won't stop.
Anyway, thank you for any input you might have.

Answer: Sergio-
There is a problem in English bulldogs with head tremors which appear
suddenly, last several minutes and then go away. Usually this will
be an
intermittent problem. I am not sure whether this is a focal seizure
disorder or if it is some other problem. It doesn't respond very well
to
traditional seizure control medications and lab work, including X-rays,
blood work and even MRI or CT examination is usually normal. In most
instances, treatment is not considered to be necessary. This problem
does
sometimes occur in other dog breeds, as well. We have seen this problem
in
dobermans, boxers and Cavalier King Charles spaniels in addition to
bulldogs.
Ear infections can sometimes cause head bobbing. I think that nausea
can do
this but that is personal opinion, I have not seen that cause listed
in the
literature anywhere. Focal seizures could potentially cause this and
might
respond to seizure control medications, if this becomes a major problem.
It
also might be a good idea to rule out low blood sugar as a potential
cause
of this problem or even better, to go ahead and run a blood chemistry
panel
to rule this out, as well as liver disease and other potential systemic
problems.
The odds are high that this is just the head tremoring syndrome that
occurs
for unknown reasons in bulldogs but being cautious and ruling out other
possible problems is a good idea.
